This lecture attempts to look at how certain groups in the plays mentioned in the title are demonised and estranged, and how they contribute to the clear definition of the dominant and the legitimate. I shall deal with ‘racism’ in these plays and outlaw sexuality, as well as the question of how these representations construct human subjects. This lecture will range across various forms of ‘illegitimacy’ and will seek to explore the ideological boundaries that they trangress with a view to exposing the fears and tensions that these theatrical representations articulate.
